便携式剂量率仪对现场废物包的定量测定

Determination of Activity Concentration of Radioactive Waste Bags With Portable Dosimeter

摘要: 为探讨放射性废物包现场的定量测量，采用便携式剂量率仪直接测量废物包的空气吸收剂量率并反推废物比活度的方法，对含^{137Cs的土壤废物包定量测量问题进行了研究，实验与理论取得了一致的结果。论述采用该方法定量测量废物包需注意的问题，同时，对测量不确定度进行了简单分析，证明了该方法是含中高能γ放射性废物包定量测量快速可行的方法之一。}

Abstract: For the determination of activity concentration of radioactive waste bags，the air absorbed dose monitoring with portable dosimeter was studied to determinate the specific activity of waste bag. The calculation and experiment got a consistent result on the study of the soil waste bag’s air absorbed dose contained¹³⁷Cs. Taking into account some special questions and uncertainty in measurement, to determinate the specific activity of waste bag by monitoring its air absorbed dose is a reasonable way.
